Narrative:
In flying back home to benkelman from a flight to blair, northeast, I had been observing radio towers that would be comparable to those that we in our business use for radio operations and for future considerations, i.e., cellular applications. I know that the telephone company in clarks, northeast, has a self supporting tower adjacent to their commercial office and wanted to get a perspective on the tower facility there, approximately 125 ft tower. In flying to clarks which is roughly between blair, northeast, and benkelman, northeast, I had dipped down to get a better view of the tower on the first pass and banked south and came around for a second and final look to better fix the details concerning the telephone company's tower in my mind. In being consumed with the details concerning the self supporting tower, I lost track of my altitude and relative closeness to the ground to the extent that I flew beneath minimums inadvertently to observe their facility.

Title: PVT PLT OF SMA SEL ACFT INADVERTENTLY FLEW BELOW THE MINIMUM PRESCRIBED ALT WHILE FLYING AROUND A COMS TWR.
Narrative: IN FLYING BACK HOME TO BENKELMAN FROM A FLT TO BLAIR, NE, I HAD BEEN OBSERVING RADIO TWRS THAT WOULD BE COMPARABLE TO THOSE THAT WE IN OUR BUSINESS USE FOR RADIO OPS AND FOR FUTURE CONSIDERATIONS, I.E., CELLULAR APPLICATIONS. I KNOW THAT THE TELEPHONE COMPANY IN CLARKS, NE, HAS A SELF SUPPORTING TWR ADJACENT TO THEIR COMMERCIAL OFFICE AND WANTED TO GET A PERSPECTIVE ON THE TWR FACILITY THERE, APPROX 125 FT TWR. IN FLYING TO CLARKS WHICH IS ROUGHLY BTWN BLAIR, NE, AND BENKELMAN, NE, I HAD DIPPED DOWN TO GET A BETTER VIEW OF THE TWR ON THE FIRST PASS AND BANKED S AND CAME AROUND FOR A SECOND AND FINAL LOOK TO BETTER FIX THE DETAILS CONCERNING THE TELEPHONE COMPANY'S TWR IN MY MIND. IN BEING CONSUMED WITH THE DETAILS CONCERNING THE SELF SUPPORTING TWR, I LOST TRACK OF MY ALT AND RELATIVE CLOSENESS TO THE GND TO THE EXTENT THAT I FLEW BENEATH MINIMUMS INADVERTENTLY TO OBSERVE THEIR FACILITY.
